The geographic poles are defined by the points on the surface of Earth that are intersected by the axis of rotation. The pole shift hypothesis describes a change in location of these poles with respect to the underlying surface – a phenomenon distinct from the changes in axial orientation with respect to the plane of the ecliptic that are caused by precession and nutation, and is an ...
NASA also cooperates with other U.S. civil agencies such as the National Oceanic and Atmospheric Administration (NOAA) and the U.S. Geological Survey (USGS) to deliver space assets supporting the weather and civil remote sensing mandates of those organizations. In 2022, NASA's annual budget was approximately $24 billion.
The Exploration Systems Architecture Study (ESAS) is the official title of a large-scale, system level study released by the National Aeronautics and Space Administration (NASA) in November 2005 of his goal of returning astronauts to the Moon and eventually Mars—known as the Vision for Space Exploration (and unofficially as "Moon, Mars and Beyond" in some aerospace circles, though the ...
The Global Geospace Science (GGS) Polar satellite was a NASA science spacecraft designed to study the polar magnetosphere and aurorae. It was launched into orbit in February 1996, and continued operations until the program was terminated in April 2008. The spacecraft remains in orbit, though it is now inactive. Polar is the sister ship to GGS Wind.
NASA: Orbiter Cancelled Canceled due to a shift in NASA's priorities, which favored crewed space missions instead. [55] The probe would have confirmed the potential existence of a subsurface ocean beneath Europa's surface, with Ganymede and Callisto also being targeted for exploration. 14 Jupiter Magnetospheric Orbiter: Jupiter Magnetospheric ...
The President stated "The directive I am signing today will refocus America's space program on human exploration and discovery." "It marks a first step in returning American astronauts to the Moon for the first time since 1972, for long-term exploration and use.
In all, 38 Discoverer satellites were launched by February 1962, although the satellite reconnaissance program continued until 1972 as the CORONA project. The program documents were declassified in 1995. [3] Discoverer 1 was a test of the performance capabilities of the propulsion and guidance system of the booster and satellite.
The Polar-orbiting Operational Environmental Satellite (POES) is a constellation of polar orbiting weather satellites funded by the National Oceanic and Atmospheric Administration (NOAA) and the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) with the intent of improving the accuracy and detail of weather analysis and forecasting.
